Sleep time is also one of the guarantees that your baby can grow successfully. Sleep is the most natural growth nutrition for babies. However, some babies have developed a “black and white” routine. The daytime whistling sleep, but at night, but abnormal spirit. As a mother, how do you correct your baby’s “black-and-white” routine? In addition to genetics, nutrition, exercise and other factors, the baby’s height is also related to the secretion of growth hormone. If the secretion of growth hormone is too low, it is very likely to cause short stature. The secretion of growth hormone has its own specific rhythm, and the peak of secretion is generally from 22:00 to 1:00 am. If you sleep too late, it is very likely to affect the height of your growing baby. In fact, the reason why the phenomenon of day and night reversal in newborns is justifiable, because the baby in the mother’s tummy for so long to live day and night, after birth always need some time to adapt to the phenomenon of day and night, for this, mothers and fathers to have patience, in fact, as long as a few weeks baby will not be so. If parents want to shorten this adaptation process, try the following methods: should let the baby will be clear day and night distinction Specific method is to put the baby in the stroller to sleep during the day, take the baby out for a walk. If you sleep in the room, there is no need to dim the light or lower the volume. When your baby wakes up, tease him or her to get him or her excited, and at night, he or she will sleep when he or she is tired. Try limiting your baby’s daytime sleep time to no more than 3-4 hours at a time. If it is not easy to wake up your baby, you can undress him or her, stroke his or her face, or tickle his or her feet. When your baby is slightly awake, you can further stimulate your baby’s response by talking or bringing toys within his field of vision. Don’t let your baby sleep after 5 or 6 pm When your baby wakes up from his nap, be sure to tease him to play for a while longer. During the daytime, the room should be as brightly lit as possible. Keep the sound inside the room all the time, you can play some soft music. Give your baby a fixed sleep cue, do the same thing before each sleep and let your baby sleep in bed afterwards. For example, give your baby a hot bath, then feed him and change his diaper. By doing this every day, every time you do these things, you will have a cue to pass to your baby: it’s time to sleep. When trying to change your baby’s daytime and nighttime disruptions, don’t get the idea that your baby will stay awake during the day and sleep quietly at night, because this is counterproductive. In fact, even if your baby sleeps a lot during the day, it is a good thing, which means that your baby is sleeping well. Changing your baby’s daytime and nighttime disruptions will take a process.
